Abstract
We surveyed incidences and clinical findings of glaucoma according to breed in 2,981 dogs presented to the ophthalmic department at the Veterinary Teaching Hospital of Azabu University from April 1994 to December 2011. Among the 21 major breeds presented, Shiba Inu dogs displayed the highest rate of glaucoma, at 42.9% (84/196). Of 121 eyes of glaucomatous Shiba Inu dogs, there were 57 eyes with corneal opacity (47.1%), 102 eyes with enlargement of the eyeball (84.3%), 66 eyes with atrophy and cuppings of the retinal optic disc (54.5%) and 50 eyes with lens luxation (41.3%). High intraocular pressure was presented in glaucomatous Shiba Inu dogs with either enlargement of the eyeball, atrophy of the retinal optic disc or lens luxation. Subluxation of the lens accounted for 90% in the glaucomatous eyeballs with lens luxation.
